Gear ISO Accuracy Grade Qg

Input Gear ISO Accuracy grade Qg with a dialog box.

Gear Measurement

Input minimum normal backlash and it's tolerance. The application determines:

Upper mean normal circular tooth thickness smn
Upper mean transverse circular tooth thickness smt
Mean chordal addendum hamc
Upper mean chordal thooth thickness smnce
Lower mean chordal tooth thickness smnci
Tooth thickness tolerance Ts
Whole depth ht

Calculated data for measurements can be printed in a measurement sheet.

Gear Load

Input of gear load with one of the following combinations:

  • Power at pinion P1 and rotational speed of pinion n1
  • Torque at pinion T1 and rotational speed of pinion n1
  • Torque at gear T2 and rotational speed of gear n2

Input with dialog:

Bevel Gear Forces

Input of cylindrical coordinates of bearing points and of mean mesh point P with following dialog box:

Bearing Points Dialog Box

Calculation of transverse tangential force Ft, the radial force Fr and the axial force Fa in mesh point and the reaction forces in supports. If the outer side of spiral of driver does'nt point into the rotation direction, the application will warn that the spiral hand is not optimal. Calculation output in a window view in table form as shown in next figure:
